Log₄32 = ln32/ln4 =3.466/1.386 =5/2 =2.5
Another method log₄(32) = x
Then 32= 4^x
but 32 = 2^5 & 4^x = 2^2x
Then 2^5 = 2^(2x)==> 5=2x & x =5/2
Answer:
i think it's 13
Step-by-step explanation:
perimeter is L+ L+W+W
27+27=54
80-54=26
26/2=13
24499.2 or rounded 24,499.2
Answer:
15x^2-14x-4
Step-by-step explanation:
(8x^2 * x-7x+2)+(7x^2 -7x-6)
you take out the parentheses
you add the common ones so -7x+-7x= -14x
8x^2 +7x^2 = 15x^2
and 2-6= -4
so in total it's 15x^2-14x-4
Answer:
40 m²
Step-by-step explanation:
square area = 4x4 = 16 m²
4 triangles area = 4x3x0.5x4 = 24 m²
16 + 24 = 40 m²
